STOVE.

Specification of Letters latent. Patent d O t 12 1920 Application filed March 26, 1920. Serial No. 368,979.

T 0 all whom, it may concern:

Be it known that I, SAMUEL S. HIPPLE, a citizen vof the United States, residing at Spring City, in the county of Chester and 1 State of Pennsylvania, have invented certain new and useful Improvements in Stoves, of which the following is a specification. 7

This invention relates to stoves for burning coal and other similar fuel and for use in heating dwellings and other similar places; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed whereby the fuel is used very effectively.

In the drawings, Figure 1 is a front view of a stove constructed according to this invention' with portions of: the perforated outer casing removed. Fig; 2 is a similar side view of the stove. Fig. 3 is a plan view of the stove. Fig. 4 is a vertical section through. the stove, taken. on the line 44 in Fig. 3. Fig. 5 is a vertical section through the stove, taken on the line 5-5 in Fig. 3: Fig. 6 is a sectional planview of the smoke drum, taken on the line 66 in Fig. 2. Fig. 7 is a sectional plan view of the fire-pot, smoke conduits and ash-pit, taken on the line 7-7 in Fig. 2. Figs...4, 5 and6 aredrawn to a larger scale than Figs. 1, 2,

3 and 7.

The base 8 of the stove is supported on legs9, and 10 is the ash-pit the bottom of which is formed by the base 8; The ash-pit door. 12 is arranged in front, andv coldair spaces or chambers 13', and smoke chambers 14, are formed at the sides and back of the ash-pit. The smoke" chambers 14 communicate with each other, and the air spaces- 13 are arranged between them and the ashpit. The fire-pot 15 is arranged above the ash-pit, and is preferablyv a rectangular box of unlined metal, and it has a fire-grate of any approved construction at its lower part.

A combustion chamber 17 is arranged over'the fire-pot, and it preferably has an arch-shaped top. The combustion chamber is wider than the fire-pot, and flat plates or flanges 18 are providedrat thetop of the 'fire-pot, where the combustion chamber is secured to it.

The combustion. chamber is connectedwith the smoke chambers 14 at the sidesof the ash-pit by means of smoke conduits 19, These smoke G0hd111t5 &16 rectangular v in cross-section, and they are 'verythin 'or narrow in proportion to their width and height. 'They have flat sides, and are substantially triangular in form, being widest at the bottom where they join onto the smoke chambers '14. .Their upper ends are about one-half as wide as their lower ends, and their upper ends communicate with the combustion chamber and conduct the smoke and other products of combustion from the combustion chamber to the smoke chams bers 14. Thesesmokeconduits 19 present a very large heating surface to the air' around them, and effect a great economy in the effective use ofthe fuel.

The base plate 8 which also forms the bottom of the cold air chambers 13 and the smoke chambers 14, has cold air inlet openby: contact with the fire-pot, ash-pit and,

smoke conduits, to pass out in which the stove is located.

A smoke drum 22 is secured above the combustion chamber 17 of the stove, and an air space 23 is formed between these parts. Perforated casing plates 24 are secured at the sides of the combustion chamber, and they permit cold air toenter the space 23. from the room independently of the inlets 20 at the bottom of the stove. Theair is heated by contact with the arched top of the combustion chamber, and portions of the heated air pass out into the room through the perforations in the upper parts of the casing plates 24.

.A hot, air pipe 25 passes vertically through the smoke drum 22, and it has a damper 26 at the top of the smoke drum. When this damper is-opened most of the. hot air from the air space 23 passes up- Wardly through the pipe 25, and may be used to heat a room above thatinwhichthe stove is located. 7 I

The hot air pipe 25 has holes 27 in its upper end portion inside the smoke drum, and an annular .air'chamber 28-is secured into the room around it and has outlet holesi29in its top .tion pass from which is a part of the top of the smoke drum 22. A portion of the heated air passes from the pipe 25 through the holes 27, chamber 28 and holes 29 into the room in which the stove is located.

The lower part of the smoke drum 22 is connected with a smoke conduit 30 by means of a short horizontal pipe or fine 31. The smoke conduit 30 is rectangular in cross-section, similar to the smoke conduits I9 hereinbefore described, and is relatively thin or narrow and has flat sides which. provide a large heating surface. The lower end portion of the smoke conduit 30 is connected to the smoke chamber 14; at the backof the ash-pit, and itis about twice as widens its upper end portion which is connected-tothe smoke drum 22,

The smoke and other products of combusthe smoke chamber 14, upwardly through the smoke conduit 30, through the smoke drum 22, and out by a smoke fine 33 at the upper part of the smoke drum' to anysuitable chimney. The smoke drum has a baffle plate 32 secured in it to 'oblige'the smoke to pass completely around the hot air pipe 25. The direction of the passage of the smoke from'the fire-pot to the chimney is indicated by the arrows in outlet for the smoke, 'a fire-pot arranged the drawings/ 7 Y The air in the room in which the stove is located is heated by contact with the back and frontsides'of the smoke conduit 30, and also bycontact with the periphery of the smoke drum,

7A by-pass smoke fine 34 is arranged be-' tween the combustion chamber 17 and the smokedrum 22, and is controlled by a suitable damper .35. This by-pass flue is opened occasionally to produce a more 'direct draft from the fire-pot to the chimney, which is desirable when a fire is being started in the fire-pot. The smoke drum has a door 36 at its front side, for cleaning purposes, and; the stove has'various other attachments such ascommonly in use on stoves of this sort.-- The conduit 30 has a damper 40.

The peculiar construction and arrange ment of the smoke conduits of this stove provide a'verylarge area of effectiveheating surface,'- the main object of the invention being to get the greatest possible heating effect with the least possible consumption of fuel. The fvarious smoke conduits and other parts can be made of cast metal or of sheet metal as found convenient.
